Trigonify brings the core tools for learning trigonometry into one focused, visual workspace. Solve a triangle, explore the unit circle, graph a function, review formulas, and practice the ideas behind each answer—without creating an account or seeing ads. SOLVE WITH STEPS • Solve right triangles with SOHCAHTOA and the Pythagorean theorem • Find missing sides and angles with clear worked steps • Use inverse sine, cosine, and tangent with domain guidance • Switch between degrees, radians, gradians, and DMS • Save solutions and return to them later SEE HOW TRIG FITS TOGETHER • Drag around an interactive unit circle • View exact values, quadrants, and reference angles • Graph sine, cosine, and tangent with live controls for amplitude, period, phase, and vertical shift • Link a moving unit-circle point to its waveform in the phase-shift playground STUDY AND PRACTICE • Search a structured trigonometry formula reference • Favorite the identities you use most • Practice by topic, review mistakes, and track streaks and accuracy • Use Exam Mode to hide solvers and answers while keeping reference tools available BUILT FOR REAL STUDY • No account required • No advertising • Light, dark, high-contrast, and reduced-motion options • iPhone and iPad support • Local app settings, favorites, history, and practice progress Trigonify is an educational calculator and study aid.
